Where Dani Goes, Happy Follows

What do you do if your best friend lives in another city and the adults can't keep their promises about when you'll see her? You have to sort it out for yourself!
Dani's father is away and Dani is staying with her grandparents. When she is invited to Ella's party, she thinks of the world's best gift for the world's best friend: she, Dani, will be the present! Her grandmother agrees—if she's brave enough to take the train alone. So Dani sets out on a journey all by herself.
